1. Check the heat pipe radiator. Small excavators work in harsh environments all year round, so there is always a lot of dust and small debris blocking the hydraulic machine heat pipe radiator and the water tank heat pipe radiator, especially when the hydraulic machine heat pipe radiator is exposed for a long time. As long as the heat pipe radiator is blocked behind the water tank, pay attention to the exposure of the hydraulic machine heat pipe radiator.
2. Check the cylinder head gasket of the mini excavator. Is there any water in the water tank during the cycle? It may be a bubble. If so, what is the p
roblem with the cylinder head of the engine?
3. Check the running equipment of the pump, and then squeeze the pipe with your hand. If the squeeze feels firm, it means that there is no problem with the pump. If it is easy to squeeze, the circulation system of the pump is not very good.
4. Check if the water tank cover is broken, which can also cause the temperature to rise. Because the water tank is integrated, water can easily enter the water circulation system, so the temperature will be higher.
5. Check if the thermostat can be opened or stuck.
6. Check if the fan speed is faster and cannot keep up with the electric pulley. This is also why the temperature can easily rise.
